CVE-2026-52371: XXL-JOB SSRF in jobinfo trigger component

CVE-2026-52371 · Severity: info · CVSS 0 · Published 2026-07-31

XXL-JOB is a popular distributed task scheduling framework used by businesses to manage and automate background jobs.

Technical details

A Server-Side Request Forgery (SSRF) vulnerability exists in XXL-JOB v3.4.0 within the 'xxl-job-admin/jobinfo/trigger' component. The vulnerability is located in the handling of the 'addressList' parameter during a job trigger request. An authenticated attacker can supply a malicious URL (such as an internal IP or a DNS logging service) to this parameter. The server then attempts to connect to the provided address, allowing the attacker to perform internal port scanning or interact with internal services that the XXL-JOB server has access to. This requires valid credentials for the XXL-JOB admin interface.
